Then there's bugs. I don't fear most of'em, but if I don't know what it is or some such, one would think that I'm deathly afraid of it. What I'm really worried about is whether or not they're poisonous.(Waking up with a poisonous spider in my bed once doesn't help this 'fear' any.
I'm afraid of dying in fire, which is strange since I'm a bit of a pyromaniac.
I think the only other thing I'm afraid of are Trolls.
